Eating olive oil increases testosterone levels in men.

Is it true that eating olive oil increases testosterone levels in men?

Unclear. One small 3-week randomized trial in 60 healthy Moroccan men found testosterone rose about 17-20% after extra virgin olive oil consumption, and a rat study found an olive compound raised testicular testosterone. A third study saw testosterone rise on a multi-component low-carb Mediterranean-style diet that included olive oil, so olive oil's own contribution cannot be separated. No item settles the general claim about men.
